PROBLEM TO BE SOLVED: To provide the detector of torque, capable of performing both the transmissions of electric power supply of a fixed side 1 to a rotary shaft side 2 and measured output of the torque detected by a load cell B6, from the rotary shaft side 2 to the fixed side 1. SOLUTION: Since a coil B1 fixed on the rotary shaft side 2 is positioned to perform electromagnetic induction at a distance L of a few millimeters in a coil A1 fixed on the fixed side 1, both the transmissions of the electric power supply of the fixed side 1 to the rotary shaft side 2 by electromagnetic between the coils A1, B1 and the measured output of the torque detected by a load cell B6 from the rotary shaft side 2 to the fixed side 1 are conducted, and various control signals are transmitted from the fixed side 1 to the rotary shaft side 2.
